170 al'l w-lwm it may-concern Be it lg-iown. that 1,. FRED. A. QB'AKEGHELDER,

a citizen of the United; States,v residing at Gambridge, in. the county of Middlesex and State ofw Massachusetts, have invented; certain. new and useful Improvements in Qan- Reshapin-g Machines, of which. the following is a specification, reference beiflg;.hfizd: to the. accompanylngr drawings, forming part.

g thereof.

This; invention, has reference to. improvementsinmachinesifor reclaiming cans; which in use have. become dented or distorted. in shape and particularly when the ensions ofi said. cans. have been reduced by indentati'ons;

The main object of the invention; lSgtO; so constructa machine of thena tune herein described that the wall of a sheet: metal can may be reshaped without..materially changingits dimensions. 7

Another objectof the invention is1to provide: a can reshaping machine in which the. introduction or removal oi the can- 13 faclh 5 tated.

Other objectsofi theinrention will appear firontthe followingdescniption.

'Ehe invention; consists. in the: novel arra-ngementv oi the reshaping rollsv and, the parts cooperatin-gtherewithi The invention also consistsin such; other novel. featuresofi construction and combina-- tion of parts as shall hereinattenbe morefully described andi pointed. out in the claims. I

Figure 1, represents a side elevation of the improved cam reshaping machine, parts: of the same being broken away. Figs. 2;, represents an end or plan view of the improved machine, the two main rolls being shown in section as on line 22 of Fig. 1.

Similar characters of reference designate corresponding parts throughout.

Cans of various kinds after some little use become misshappen by reason of the indentation of their walls from blows. In most cases the use of cans having such indentations reduces materially the dimensions of the cans and, in all cases, the use of cans having indentations is objectionable. In actual practice it has been found difiicult to smooth out the sheet metal wall of a can having indentations without so upsetting the material of the wall that the dimensions of the can operated on are changed, usually by reducing the diameter of the can somewhat.

In carrying my: invention into practice. I,

provide a machine in which the reshaping oi the-wall of a can,tofiatten. or smooth out indentations therein, isefiected by rolls and inasuch; manner that the tendency of the wall oiithe can to contractis ofi'set by the exerti'on continually of. a slight outward strain on vsaid; wall during the rolling process. and I provide means. for facilitating the operab10112 0n. the can.

In the embodiment of my invention dis-.

closed in, the acco'mpanyingdrawings?) in-.

dicates. a substantially rigid base. or supporting member for the operating mechanism Thisibaseb is shown. in. thedrawi'ngs asextending vertically and as adapted tobe secured to. another upright member but if preferred, such, base: 5 may extend horizontally. Mounted on said; base. 5 are the plates 6; and 7- of which. plate Boyhas the frame 8 hav ng the pressu e. sc ew 9 andthebearing blocks. 10* and 1-1 the latter of which. is centered in frame 8 by the side; bearin s rews as. l2 and. hasa socket to receivethe pr ss rescrew Pla h sthe rames 13 having; the ads jnsting screw 14: and the side-bearing. screws 15,15; Pivotally connected-with the Screw Lhis the; rigidlink l6twhich in turn is-pivotally connected by the-link 17, having the leverhandle18, with the stem? 19 of the shaft.

bearing member '20 which latter is centered between the side=screws 15,.15-but iscapable of. movement in line with. its stem 19 when the latter is moved bythe, swinging of link 17 effected by means of its lever handle. 18., Said frame 13. is; provided. with the cross bar 21 which is adapted to limit the endwise movement of long cans and said frame 7 has the bearing member 22 which cooperateswith a somewhat similar member 23, located on plate 7 at a distance from the frame 13, to rotatably support the small rolls 24, 24, having grooves as 25. On said plate 7 are mounted the pairs of arms 26, 26 having at their upper ends the rails 27, 27 mounted for adjustment relative to the diameter of a can to be received therebetween.

Journaled in the bearing blocks or members 10, 22 and 23 is the main roll 28 having the flange 29 and the circumferential grooves 30 and 31, and the gear 32. Provision is made for rotating this roll 28 in any suitable manner, herein shown as the pulley 33 mounted on said roll 28 and adapted to be its gear 36 with the gear 32 of the roll 28.

By the swinging of the lever handle 18 from the position shown in Fig. 1 the link 17 is swung to relieve the pressure exerted thereby on the bearing member 20, through its stem 19, and to draw said bearing member 20 and the pressure roll 35 away from roll 28 sufliciently to permit the can G to be placed in position over the end of the pressure roll 35 with its exterior annular rib 0 and its bottom joint 0 received in thegrooves 30 and 31 respectively of the roll 28 which grooves constitute clearances for said'parts 0 and c. The rib c of said can 0 is also received by the grooves as of the rolls 24, 24. Such position of the can 0 is facilitated by the rails 27, 27 which when adjusted to bear slightly against the 25 can also assist in preventing lateral movement of the can. Lever handle 18 is now swung to the position shown in Fig. 1 and,

by such movement, link 17 is brought into alinement with link 16 and stem 19 and bearingmember 20 with its roll is forced toward roll 28 and said roll-35, operating against'the inside of the wall of can C,

forces said wall into contact with the peripheryv of roll 28 between the rolls 24, 24. In such position the flange 29 overlaps the bottom end of can 0 and prevents the endwise movement of said can in one direction.

Rolls 28 and 35 are now caused to rotate and said rolls being frictionally engaged with the wall of the can 0 cause said can to rotate and at the same time compress and smooth out any indentations or rough portions in the wall of the can while the rolls2 l,

24 act as rotatable guides for the can and so sustain the wall of the can that the pressure of roll 35 tends to press the wall of the can radially. After such reshaping of the can C, the lever handle 18 is swung to the release position and the can is removed endwise from the machine.

Having thus described my invention I claim as new. and desire to secure by Letters Patent.

1. A can reshaping machine comprising a base, frames on said base having bearings, a pressure roll journaled in said bearings and having a peripheral flange at one end and a pair of grooves, a second pressure roll journaled in bearing members carried by said frames, one of said latter bearings being movable, means for moving said latter bearing and its roll toward and from said first roll, means for rotating one of said rolls, and a pair of guide rails adjustably mounted at the sides of the machine and adapted to receive between them a can to be operated on.

2. A can reshaping machine comprising a base, frames on said base having bearings, a pressure roll journaled in said bearings and having grooves to receive exterior projections of the can under operation, a pair of grooved rolls journaled in bearings at the sides of and above the axis of said first pressure roll, a second roll journaled in bearings of said frames, one of which latter bearings being movable, adjustable centering means for said latter bearing, a rigid stem extending from saidmovable bearing, a link adjustably mounted relative to said stem, a second link pivotally connected with said first link and with said stem and having a lever, and means for operating one of said pressure rolls.
